How does DOI lookup work?
Search a title or reference, or resolve an existing DOI directly. Exact title matches come first; check authors and year too.
What if there is no result?
Some real sources have no DOI or are outside Crossref coverage. Check the publisher; no result is not proof of fabrication.
